Tried to update again, because this line gave me hope:Everyone please check 1st post. Both menu and Firmware have been updated.
Darksoft's MultiMVS Latest Firmware, Menu and Instructions
* Fixed and error where If the flash memory on the MVS board is empty or has incorrect data describing the FPGA configuration, it was not possible to upload a new FPGA configuration and use the basic MVS functionality (NEW in this version)
However it still does not work. I'll be packing and sending my cart ASAP.
